Windows Update Standalone Installer Error

2016/11/30

I had to install PowerShell 3.0 on my Windows 7 SP1 VMware Fusion 8.5 VM earlier today and grabbed the installer from https://www.microsoft.com/en-us/download/details.aspx?id=34595. The download was done from Chrome on my Mac and saved to my Mac’s Downloads folder.

I have Shared Folders running in Fusion so I have direct access to the Downloads folder from Windows via the Z:\ drive presented to Windows.

When I ran the .msu file from z:\downloads I would receive an error which said:

Installer encountered an error: 0x80070003
The system cannot find the path specified.

The fix is to copy the .msu file to a VMDK based disk in the VM and run it again.

2016/11/15

Problem: I wanted to know what proxy my Mac was using for Internet access.

The advanced settings in the Network cdev had Proxies set to “Auto Proxy Discovery” however I could not find a way to make my Mac tell me what proxy servers it had discovered and was using.

Solution: Chrome has a nifty command that will cause it to output its proxy configuration. Enter the following into the address bar.
